Satellite Seafloor Mapping Services

Our satellite seafloor mapping services deliver rapid analysis of coastal topography, seafloor morphology and satellite derived bathymetry in shallow water. These insights help optimise your marine development projects and asset management.

Fugro’s satellite seafloor mapping services leverage satellite-based remote sensing technology to visualise the seabed morphology and derive ocean bathymetry data, topography and benthic zonation rapidly for large spatial areas. Combined with our in-house geoconsulting expertise, data analytics and processing algorithm, we deliver early insights into the seafloor and nearshore environments that enable you to maximise project timelines and reduce risk for nearshore development projects anywhere in the world.

Our proven approach for satellite seafloor mapping uses multispectral satellite imagery to map shallow water environments with suitable water clarity. The data is captured in near-real time to acquire an up-to-date representation of the coastal topography and seabed morphology. Additionally, a dynamic assessment of the seafloor can be made by our experts using multiple years of representative multispectral satellite imagery. Using data analytics and processing algorithms, bathymetry and benthic zonation can be derived for a quantitative analysis.

SatRecon®

SatRecon® provides qualitative site reconnaissance based on satellite imagery for fast visualisation of the site and visual change detection in shallow water. Typical deliverables are:

  • Preliminary site reconnaissance imagery including hazards and obstruction visualisation
  • Seabed reconnaissance images
  • Qualitative safety assessment for navigation
  • Visualisation of morphology dynamics and storm impact with time-series

SatAnalytics

SatAnalytics uses satellite data from various providers to derive quantitative deliverables for planning and change detection in shallow water. Typical deliverables are:

  • Satellite-derived bathymetry at 10 m or higher resolutions for safety of navigation or seabed change detection
  • Seabed mobility assessment including modelling via webGIS
  • Seabed morphology mapping (using sub surface irradiance reflectance)
  • Habitat mapping
  • Remote topography (DEM/DTM) at 2 m resolution
  • Shoreline dynamics (time-series analysis, determination of high and low water marks)
  • Water surface obstructions
  • Land use and cover classification
  • Environmental conditions analysis, such as organic matter, algae bloom, secchi disk, water surface temp, turbidity etc. to plan for suitable technology to be deployed and the best time to acquire high-quality lidar data

Fugro’s satellite seafloor mapping services deliver fast and early insights into nearshore sites for various applications including change detection, preliminary survey planning, landing site evaluation and selection, identification of hazards and obstructions and description of natural conditions (e.g., habitat, seabed, geology and turbidity) among others. These applications support shallow water survey requirements at various development phases of your project. 

Desktop and feasibility study

We provide essential information and analysis, such as potential hazards and obstructions, historical morphological changes, and coastline dynamics, etc. to identify constraints when evaluating suitability of the site for route corridors, landfall sites or any infrastructure developments. A preliminary model of the nearshore site can be derived by integrating satellite-derived bathymetry in shallow water with a digital terrain model for preliminary quantitative analysis needs during the feasibility study.

Detailed site investigations, design and installation consulting

Our experts can perform remote site reconnaissance to analyse extensive areas of current and historical information of the nearshore site. The details obtained can be used to determine the survey programme for the subsequent site investigation and complement the findings from conventional site visits to identify any critical features of the site. We also provide geoconsulting services to help you optimise your site investigation scope, enhance project development timelines, and ensure high-quality site investigations. We also provide historic satellite imagery analysis that allows for modelling of multiple scenarios (e.g., seasonal scour scenarios and the larger coastal area beyond the project site) to help you make more informed decisions in the overall design and minimise project risk.

Operation and maintenance for assets located in shallow marine environment

Our advanced technologies achieve detailed coverage of the seafloor that supports monitoring of the surrounding environment for your assets throughout the operational life cycle, such as seabed change detection and using satellites to collect ocean bathymetry data to measure an impact assessment after storm events. Monitoring frequency can be defined and adjusted based on the anticipated morphological and sediment dynamics of the site. The near real-time information obtained from the satellite remote mapping can also be used to plan operations and maintenance for the asset in shallow marine environments.

  • Project milestone assurance and efficient operations planning through early seafloor reconnaissance and feasibility assessment with site-specific data before vessel-based site surveys are undertaken
  • Operational risk reduction by improved insight into the morphological dynamics and the impact on the asset during its lifetime
  • Reduced HSSE exposure and CO2 footprint enabled by remote or virtual site visits
